Hi,
I tried to run libvirt-1.0.2 with LXC as below, but it failed to mount cgroup.
You should change your cgroup configuration as below cgroup on /sys/fs/cgroup/cpuset type cgroup (rw,nosuid,nodev,noexec,relatime,cpuset) cgroup on /sys/fs/cgroup/cpu,cpuacct type cgroup (rw,nosuid,nodev,noexec,relatime,cpuacct,cpu) cgroup on /sys/fs/cgroup/memory type cgroup (rw,nosuid,nodev,noexec,relatime,memory) cgroup on /sys/fs/cgroup/devices type cgroup (rw,nosuid,nodev,noexec,relatime,devices) cgroup on /sys/fs/cgroup/freezer type cgroup (rw,nosuid,nodev,noexec,relatime,freezer) cgroup on /sys/fs/cgroup/net_cls type cgroup (rw,nosuid,nodev,noexec,relatime,net_cls) cgroup on /sys/fs/cgroup/blkio type cgroup (rw,nosuid,nodev,noexec,relatime,blkio) cgroup on /sys/fs/cgroup/perf_event type cgroup (rw,nosuid,nodev,noexec,relatime,perf_event)
Libvirt lxc doesn't support configure cgroup as you did below now.
Why? IIRC old systems mount cgroup at /cgroup by default. This means libvirt lxc has backward compatibility on supporting cgroup?
I think it is due to the upstream kernel change, which is merged in 2.6.36 version. Discussion thread here for your reference. http://thread.gmane.org/gmane.linux.kernel/1013171 -- Qiu Yu
